StarOffice 8 (Product 6) Update to Product 7 Error

Question

Hi,
I tried to update as prompted by auto-update feature. But after I have finished downloading and saved the file 120187-10 (Signed Patch). But when I opened the file, a Java virtual machine launcher window pop up and with message stated Invalid or corrupt jarfile.
I have downloaded the latest version of Java(TM) SE Runtime Environment 6 update 1 and tried the 2nd time but failed also, with the same error message.
Can anyone pls help what could be the cause having this update error?
Thanks.

The StarOffice team has provided the following feedback regarding your
inquiry:
Each patch is provided as common .zip file
(http://sunsolve.sun.com/pub-cgi/pdownload.pl?target=120187-10&method=h)
and as signed .jar file
(http://sunsolve.sun.com/pub-cgi/pdownload.pl?target=120187-10&method=hs
The signed link is just below the common link on the StarOffice Patch
site on SunSolve.
Having signed .jar files is a default behavior of SunSolve, each patch
we submit is automatically places as common and as signed one. Customers
can read more details when the click on the "Help" link on the right on
SunSolve. On the following page item 8. lists the link

tches.
From there customers can read the following:
(A8) Signed and unsigned patches are simply two different packaging
formats of the same patch. Signed patches are in a jar file format and
unsigned patches are in a zip file format. The contents of the files
are identical except that the jar file format also includes signature
files. Signed patch files can be verified with the Java jarsigner
command as follows:
jarsigner -verify <patch number>.jar
The command jar -x would extract a .jar file.
